670B Power Supply and Display with Signal Conditioner

The 670B Signal Conditioner/Display/Power Supply provides full control of all High Accuracy Baratron® manometer features. All functions can be monitored and controlled via the RS-232 interface. Range switching can be done manually or automatically by selecting the lowest possible on-scale range. The 670 may be used with any sensor Full Scale and will display pressure in any one of 12 engineering units.

Supports 120A, 615A, 616A, 690A, and 698A High Accuracy Baratron® transducers
Analog and digital I/O signals interface with computers and process control systems
Two built-in alarm relays provide process pressure trip points

Features

Pressure Transducer Signal Conditioning

The 670B power supply and display can be used to optimize the pressure readings for transients or noisy pressures. Sensor response time may be set for 1, 40, 400 msec, and a data averaging feature allows the user to average signals from 0.1 to 10 seconds.

Accessories

Three-Channel Sensor Multiplexor

The 274B Three-Channel Sensor Multiplexor allows a single 670B signal conditioner to operate as many as three (3) high-accuracy Baratron® sensors.
